INTERNAL RESORPTION:-

DEFINATION:-

Internal resorption is an idiopathic slow or fast progressive resorptive process occuring in the dentin of pulp chamber or in the root canals of the tooth.


ETIOLOGY:-

  • Exact etiology is not known
  • Patient often presents with history of trauma or persistent chronic pulpitis, or history of pulpotomy

mecanism of resorption


SYMPTOMS:-

  • Usually asymptomatic , recognized clinically through routine radiograph
  • Pain occurs in cases of perforation of root
  • Pink tooth is the pathognomic feature of internal root resorption

HISTOPATHOLOGY:-

Histopathology


DIAGNOSIS:-

Clinically:- "pink tooth" appearance

Clinical Appearance of Internal Resorption

Radiographic changes:-

  • Radiolucent enlargement of pulp canal.
  • Original root canal outline is distorted.
  • Bone changes are seen only when root perforation into periodontal ligament takes place.

Pulp tests:- Positive, though coronal portion of pulp is necrotic, apical pulp could be vital.


TREATMENT:-

  • Pulp extirpation stops internal root resorption.
  • Surgically, treatment is indicated if conventional treatment fails.
